The Rambler® 18 oz. Bottle is a necessary addition to your morning hikes, kayak trips, and daily commutes. This tough bottle is double-wall vacuum insulated to keep your water cold until the last sip, dishwasher safe for easy cleaning, and comes standard with the Chug Cap. With a quick twist, the TripleHaul™ handle comes off, exposing our shatter-resistant, dishwasher-safe spout that allows for controlled gulps on the go. When it's time for a wash or refill, remove the entire cap to expose the bottle's wide mouth. Made with kitchen-grade stainless steel, so they're puncture- and rust-resistant. Double-wall vacuum insulation keeps cold drinks cold and hot drinks hot until the last sip.
